What does cc.models.UserProfile looks like ?

This should be :

... except cc.models.UserProfile.DoesNotExist:

As a general rule:
* NEVER use a bare except clause unless you reraise the SAME exception
in the except block.
* always catch the most specific exception type.

Given the above statement, I assume the "models.py" file you're
talking about is not the one where you define your UserProfile class.
If yes - you may have legitimate reasons to split this between
different apps -, are you sure the models.py file where you set up
this signal handler is correctly registered and imported ? (hint: is
the app containing this models.py in your settings.INSTALLED_APPS ?)

FWIW, you can insert print statements (poor man logging) in your
models.py file to make sure it's imported and check if the signal
handler is executed:

# wherever/models.py
from django.db.models.signals import post_save

print "in %s" % __name__

def profile_handler(sender, **kwargs):
""" Signal handler to deal with a save on the User model """
try:
p = sender.userprofile
print "in %s : for user %s, profile %s already exists" %
(__name__, sender, p)
except cc.models.UserProfile.DoesNotExist:
profile = cc.models.UserProfile(user=sender)
profile.save()
print "in %s : for user %s, created profile %s " % (__name__,
sender, p)
except Exception, e:
print "in %s : for user %s, got unexpected exception %s" %
(__name__, sender, e)
raise

print "in %s : connecting profile_handler to post_save signal" %
__name__
post_save.connect(profile_handler, sender=User)
print "in %s : connected profile_handler to post_save signal" %
__name__

Running this with the builtin dev server should provide some useful
informations about your problem.
